To ZZ whom 'it may concern.'

Bc it known that l, riisnnuw J. Hrrorreook, a citizen of the United States oi America, and residento Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Non-Refillable and Self-Glosing Bottles, of which the following is a specification.

This invention relates to bottles and particularly to non-reiillable Aand self-closing Stoppers or guards for such bottles.

An object of this invention is to provide novel means whereby the mouth of the bottle is automatically closed when in upright position or when in approximately upright po sition so that the mouth of the bottle is guarded to prevent the delivery of material to the said bottle, thus preventing the refilling of the said bottle.

A further object of this invention is to provide novel means whereby the closure is held seated on a shoulder at the mouth of the bottle so that in handling, shipping or the like, the closure or stopper cannot be accidentally displaced.

A still further object of this invention is to provide a bottle of the character indicated in which the guard and stopper is secured to the bottle by mechanism which is simple in construction and comparatively inexpensive, thus enabling the producer to furnish bottles at comparatively small cost.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

1n describing the invention in detail, reference will be had to the accompanyingdrawings forming part of this specification wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a view in elevation of a bottle showing the casing for the guard and stopper also in elevation;

Fig. 2 illustrates a vertical sectional view of the guard and stopper associated with a fragment of a bottle;

Fig-3 illustrates a sectional view on a line 3-3 of Fig. 1; and

Fig. 4 illustrates a. sectional view on the line P4 of Fig. 1.

In these drawings 5 denotes the bottle, 6 the neck thereof, said neck having a circumferential groove or seat 7 in whicha flange 8 of a ring 9 is partially embedded, the said ring constituting a fastening by which the valve casing 10 is secured in place, it being shown in the drawing that the lower end of the said valve casing is provided with a circumferential groove 11 forming a seat in which the upper flange 13 of the said ring 7 is partially embedded, thus making a joint between the neck of the bottle and said casing which will prove effective in retaining the said casing in place.

The interior of the said casing is supplied with a series of vertically disposed ribs 13 which constitute guides for the combined guard and stopper 14, the movement of the said guard and stopper being limited by reason of the presence of the shoulders 15 which are formed near the upper ends of the guides. The upper end of the neck constitutes a shoulder or valve seat 17 on which the member 14 is seated when the bottle is in approximately vertical position, it being understood that the said member 14 will automatically engage the said seat by' gravity so that when the bottle is in position for liquid to flow into it, the member 14 will be seated so as to prevent the liquid from reaching the interior of the bottle.

The interior of the casing is further provided with a cross bar 18 having an aperture 19 in which a stem 20 is guided and the upper end of the said stem 20 is confined by a guide 21, the aperture 22 oi which is relatively deep so that the end of the stem is within the area of the said aperture when the member 14 is seated.

A cap 23 is provided with threads 24 which engage threads 25 on the casing and the said cap is further provided with a depending stud or lug 2G which is adapted to bear against the upper end of the stem 20 when the cap is screwed on the casing, the said engagement affording sufticient pressure to hold the member 14 on the seat or shoulder of the neck of the bottle, thereby closing the said bottle for the purposes heretofore stated.

The construction, operation and advantages will, it is thought, be understood from the foregoing description, but it will be apparent that when the cap is removed, the closure 14 may, when the bottle is tilted, unseat and permit the outflow of the contents of the said bottle, whereas upon righting the said bottle, the closure will automatically seat to guard the mouth of the bottle where- :is the reupplication of the cap and the cusing will result in pressing the said closure and holding it against accidental displacement.

I claim- In a closure for bottles, :L bottle having a, circumferential groove near its upper end, a casing having a groove, said casing resting on the bottle, a. securing ring having flanges partially embedded in the groove of the bottle and the groove of the casing,

guides on the interior of the casing, a combined guard and closure adapted to seat on the neck Vof Vthe bottle7V a stem projecting from the closure, a guide having an aperture into Which the upper end of the stein extends, a cap for the casing, and a member depending from the cap and extending into the guide for engaging `the end of the stem for holding the closure in place.
